Fitting Recaros from another car to clio 200?

Ideally I would like to purchase some corsa VXR recaros as they are similar to the clio ones but the bolsters don't wear as much and they are more widely available 2nd hand.

How easy would it be to fit these to my car?

Would it just mean removing the subframes and fitting them to the clio subframes? how hard is this?

Also.. A lot of the Corsa VXR recaros come with the matching rear seats, do these fit in the clio size wise? and how hard would they be to modify to install?
